Work vehicle

Abstract

A tractor includes a mounting plate, a protruding tube, a boom supporter, and a boom. The mounting plate is attachable to a frame on a side surface of a vehicle. The protruding tube is connected to the mounting plate, and shaped to protrude from a portion in which the protruding tube is connected to the mounting plate, toward the outside of the vehicle. The boom supporter is connected to a distal end portion of the protruding tube, and shaped to protrude upward from a portion in which the boom supporter is connected to the distal end portion of the protruding tube. The boom is coupled to the boom supporter via a boom coupler, and formed to extend from the boom coupler toward the front side of the vehicle. In a side view, an imaginary straight line extending vertically downward from the boom coupler is located rearward of the protruding tube.

1. A work vehicle comprising:
 a mounting plate attachable to a frame that is on a side surface of a vehicle body; 
 a protruding member that is connected to the mounting plate and shaped so as to protrude from a portion in which the protruding member is connected to the mounting plate, toward the outside of the vehicle body; 
 a boom supporter that is connected to a distal end portion of the protruding member and shaped so as to protrude upward from a portion in which the boom supporter is connected to the distal end portion of the protruding member; and 
 a boom that is coupled to the boom supporter via a coupling part and formed so as to extend from the coupling part toward the front side of the vehicle body, wherein: 
 in a side view, an imaginary straight line extending vertically downward from the coupling part is located rearward of the protruding member, 
 the boom supporter includes a lower boom-coupling member positioned at a lower side and an upper boom-coupling member positioned at an upper side, 
 in a side view, the lower boom-coupling member protrudes upward and rearward from the portion in which the lower boom-coupling member is connected to the protruding member, 
 in a side view, the upper boom-coupling member protrudes upward from a portion in which the upper boom-coupling member is connected to the lower boom-coupling member, and 
 a reinforcing member, which is connected to the mounting plate and the lower boom-coupling member to thereby provide reinforcement, is provided rearward of the protruding member. 
 
     
     
       2. The work vehicle according to  claim 1 , wherein the reinforcing member is connected to the lower boom-coupling member, near the portion in which the lower boom-coupling member and the upper boom-coupling member are connected to each other. 
     
     
       3. The work vehicle according to  claim 2 , comprising:
 a floor on which an operator can put his/her feet; and 
 a floor extension member that is connected to a front portion of the floor and provided in an interior space formed above the reinforcing member and inside the boom supporter. 
 
     
     
       4. The work vehicle according to  claim 3 , comprising a hydraulic pipe that supplies hydraulic oil to a hydraulic unit, wherein
 the hydraulic pipe passes through the interior space. 
 
     
     
       5. The work vehicle according to  claim 4 , wherein
 the hydraulic pipe is disposed below the floor extension member. 
 
     
     
       6. The work vehicle according to  claim 4 , comprising a hydraulic coupling disposed below the floor, wherein
 the hydraulic pipe passes below the floor extension member and above the reinforcing member, and is connected to the hydraulic coupling.
